I was terrified for this young woman and that was the only reason I watched to the end. Being a Tilda fan, I wanted to see what her daughter could do too! I stopped trying to make any sense of the conversations. When she was sick, I still don't now why. I thought it was the dope fiend's fault. Whewww at least she made it through the film.
You have to be ready to rewind and try to make sense of it all. Slow paced but so unintentional, like it's just improv.
